Our guests were Soll Sussman, Managing Director, S Cubed Studio, and Erika Benson a Partner in Gardereâs Government Affairs Practice Group in Austin. We discussed the upcoming 19th US â Mexico Border Energy Forum in Hermosillo, Sonora Mexico. Soll Sussman has been the organizer for the Forum since its beginning in 1993. The State of Texas General Land Office has been a supporter of the event since the beginning, mainly because it helps promote trade and development of Texas and Mexico energy resources. The emphasis of the forum is on renewable energy and energy efficiency solutions for the border regions.
